Scientists can study Earth’s climate as far back as 800,000 years by drilling core samples from deep underneath the ice sheets of Greenland and Antarctica. Detailed information on air temperature and CO2 levels is trapped in these specimens. Current polar records show an intimate connection between atmospheric carbon dioxide and temperature in the natural world. In essence, when one goes up, the other one follows.

There is, however, still a degree of uncertainty about which came first—a spike in temperature or CO2. Until now, the most comprehensive records to date on a major change in Earth’s climate came from the EPICA Dome C ice core on the Antarctic Plateau. The data, covering the end of the last ice age, between 20,000 and 10,000 years ago, show that CO2 levels could have lagged behind rising global temperatures by as much as 1,400 years. “The idea that there was a lag of CO2 behind temperature is something climate change skeptics pick on,” says Edward Brook of Oregon State University’s College of Earth, Ocean and Atmospheric Sciences. “They say, ‘How could CO2 levels affect global temperature when you are telling me the temperature changed first?’”

I must say I have been rather disappointed at the scientific coverage over the past few years. You would think there were no other pollutants than carbon dioxide. The Government thought so, as they generally do not posess science qualifications. And Volkswagen seemed to think so too. So they cheated. . What happened to the black footprint printed on every packet? That "drowning" rabbit advert was pulled pretty quickly. All very silly.

Anyway without any silly Government intervention, we all now have LED lighting, and flat TVs.

The climate has always been changing.....why, we were under water once, the ice age...but people are not helping matters by the things they are doing to their world.... globally our only home is not being respected it is being used and abused.

That is very silly, but California is the silliest of the states. Methane might be more of a problem than CO2, but's always been there.

In a time before God invented people, there must have been millions of tons of farting meat, whether ants or dinosaurs. I really don't see what senators can do about bovine flatulence. Let's hope they have their Canute moment.

I never understood the push for diesel even from a climate change perspective as whatever savings arising from Co2 emissions are cancelled out by NoX emissions. NoX group gases are much more potent global warming gases than Co2.

Climate change aside Diesel Particulate Matter is the 21st Century Asbestos - said that on here years ago before DPM was formally classified as a Carcinogen.

Possibly! I've never had a Diesel car. Friend of mine is actually an environment biologist, and doesn't want one either. He was saying this 20 years ago. I have no idea whether Nox does global warming, but it's not good to breathe. Also the soot particles might be dangerous.
